We have spent as little as $15 - $20 a day for our family of 5 in the early years (no meals in the parks, a snack or two to share, brought water and sandwiches, etc in with us) up to $300 a day for all food and beverages. If we stay on property, we get the dining plan, if we stay at our condo, we skip the dining plan and still have a few meals at our favorite restaurants throughout the week. Check the restaurant listings in Unofficial guide, it lists the price ranges for each restaurant. Whatever you plan on, add extra. We usually spend more than planned.
